Christchurch's Mayor-elect Lianne Dalziel has asked the council why information regarding a murder victim has not been released to the woman's family.
Valmai McFie, 67, was stabbed to death by her neighbour Colin Albert Hoani, 59, at a council housing complex on July 20 after she allegedly made a racist comment towards him.
There had been an acrimonious history between the pair, and Mrs McFie's family has since raised questions why the murder was allowed to happen given that she had raised fears over living near Hoani in the past.
Last week Hoani was sentenced to a life sentence with a minimum non-parole period of 10 years.
During sentencing in the High Court at Christchurch, Mrs McFie's niece Louise Wegner said her aunt had raised concerns about Hoani for more than 12 months, saying he was a "source of discontent''.
